Michael Dougherty
Aliases used:
Jim Jones– name he continues to use to victims’ families
fieldnotes– name used on WS
J.J.Fieldnotes– name used for blog
TheForeigner– name used on WS portraying a “foreign woman”
(Edit: based on new evidence, I have doubts that TheForeigner is an alias of Michael Dougherty’s.)
There are likely more, but those are the most commonly used.
